摘要
描述了临近空间飞行器测控雷达天线对波束尖锐度的要求,受单脉冲雷达天线技术启发,提出一种新型天线波束锐化技术方法,并经半实物仿真结果验证,在缩小天线辐射口径的情况下,同时使天线的主波束十分尖锐,理论上可以大大提高测控雷达的对地分辨率,同时更加符合实际工程应用需求。
The requirements of beam sharpness of telemetry and control radars for near space vehicles are described. Enlightened by the monopulse radar antenna technology, a new technology for antenna beam sharpness is presented. Simulated results are demonstrated that the antenna＇s main beam is quite sharp in the reduction of the iation aperture of antenna. Theoretically, the technology proposed in this paper can increase the ground resolution of the telemetry and control radars, which is more correspond with the actual engineering appli- cation requirements.
